2: Clarification mechanism of coagulant

Chemical coagulation is a process in which chemical agents (coagulants) are added to water treatment to make colloidal dispersion system destabilize and agglomerate. In the coagulation process, small suspended particles and colloidal impurities are aggregated into larger solid particles to separate particulate impurities from water, which is called coagulation clarification.

After adding coagulant into water, colloidal particles and other small particles can be polymerized into larger flocs through the comprehensive action of mixing, coagulation and flocculation. The whole process of coagulation and flocculation is called coagulation.

(1) Destabilization and condensation of colloids

Adding electrolyte to water can compress the electric double layer and destabilize the colloid. The main mechanism is that the electric double layer of colloidal particles in water is compressed or neutralized by adding aluminum salt or iron salt coagulant. The coagulant and raw water are mixed rapidly and evenly, and a series of chemical reactions are produced to destabilize. This process takes a short time, generally about 1 min. Some cationic polymers can also play a role in the destabilization and condensation of colloids in water. These polymers have a long chain structure and positive charge in water. Their destabilization and condensation of colloids in water is due to the interaction of van der Waals force adsorption and electrostatic attraction.

(2) Flocculation and formation of floc (alum)

The particle size of the initial flocculate formed by colloid destabilization and coagulation in water is generally more than 1 m. at this time, Brownian motion can no longer push them to collide and form larger particles. In order to make the initial flocs collide with each other to form large flocs, it is necessary to input additional energy into the water to produce a velocity gradient. Sometimes it is necessary to add organic polymer flocculant into water, and the adsorption bridging effect of long chain molecules of flocculant is used to improve the probability of collision and adhesion. Flocculation efficiency usually increases with the increase of flocculate concentration and flocculation time.

Compared with polyaluminum chloride, polyaluminum chloride has the advantages of high density, fast settling speed and wide pH adaptability; the coagulation effect is less affected by temperature than that of polyaluminum sulfate; however, when adding ferric salt, it should be noted that when the equipment is not in normal operation, the iron ions will make the effluent color, and may pollute the subsequent desalination equipment.

Corrosion can significantly weaken a drainage system, leading to costly repairs and potential hazards.


  • Ease of Cleaning


  • Another significant advantage of smart dustbins is their potential to promote cleanliness and hygiene in urban environments. Traditional dustbins often attract pests and can create unpleasant odors when they overflow, leading to unsightly litter in public spaces. Smart dustbins, equipped with features such as compactors, can help reduce the frequency of overflowing containers, thus maintaining a cleaner environment. Additionally, many smart dustbins are designed with sensors that can detect when they are about to overflow, triggering an alert for immediate collection and preventing unsightly litter from accumulating in public areas.

Because pipes can be accessed quickly, repairs can be conducted with minimal interruption to service. This efficiency is not only time-saving but also cost-effective, reducing the labor costs associated with extended maintenance periods.


  • One of the primary reasons gully lifting is necessary is to mitigate erosion. Gullies are naturally occurring channels that develop due to water flow, which can lead to significant soil loss over time. When heavy rainfall occurs, water can erode the sides of these gullies, causing them to widen and deepen. This process not only diminishes the land's agricultural viability but also contributes to sedimentation in nearby bodies of water, adversely affecting their quality and the aquatic life they support.


  • - Concrete Heavy-duty and robust, concrete drain covers are often used in industrial applications. They can be cast to meet specific sizes and load ratings but are more challenging to install and replace due to their weight.

Whether in residential, commercial, or industrial settings, the durability and reliability of pipe connections are paramount. A simple yet effective solution for leaks and breaks, the 1% pipe repair clamp offers a practical answer to what can sometimes be a significant inconvenience.


  • In the world of drainage systems, the 8% wide trench drain has emerged as a highly effective solution for managing excess water in various environments. This system is particularly designed to facilitate the swift and efficient removal of surface water runoff, thereby preventing flooding, erosion, and other water-related challenges.


  • In addition to their practical applications, bollards and ropes can serve an artistic purpose as well. Designers and city planners have the opportunity to use varying colors, materials, and forms to create visually striking elements that reflect the character of the area. In an age where public art is becoming increasingly valued, these features can contribute to the cultural narrative of a city. Community engagement in the design process can further enhance this aspect, allowing residents to feel a sense of ownership and pride in their surroundings.


  • It's also worth considering the impact of bulk purchasing. Many suppliers offer discounts for larger orders, which can be particularly beneficial for contractors working on extensive projects. Negotiating with suppliers can often yield better pricing, especially for recurrent buyers.


  • Furthermore, rubbish bins are often utilized in urban planning as a tool for managing waste more effectively. Cities that have implemented comprehensive waste management strategies, including the placement of bins, tend to have cleaner streets and healthier environments.
